Which has stronger attractions among its submicroscopic particles: a solid at 25°C or a gas at
A)The attractions among the submicroscopic particles of the solid must be stronger than the attractions among the particles of the gas.
B)The submicroscopic particles of the gas are moving faster. This means that they have more energy, which means that the attractions among them must be stronger.
C)The attractions among the submicroscopic particles of the solid are much stronger, so much stronger that they hold the particles of the solid absolutely still.
D)The temperatures of these two materials are the same, which means that the attractions among their submicroscopic particles are also of the same strength.

Quizplus · Accepted Answer

A solid has stronger attractions among its submicroscopic particles compared to a gas because in a solid, the particles are closely packed together and have less kinetic energy. This means that the intermolecular forces of attraction, such as van der Waals forces, are stronger in a solid than in a gas. In a gas, the particles have more kinetic energy and are more spread out, so the intermolecular forces of attraction are weaker. Therefore, option A is the correct answer.
